Using ARCH variable to select different configurations for the different
architectures is misleading and conflicts with the variable ARCH being used by
the build system. The variable is not needed, it is application specific and
an application can be built without the need to specify ARCH on the command
line.
This is yet another item specific to samples and test cases that
wrongfully being used and documented for every application. We need to use
another variable and just make it clear it is specific to samples and how they
are written. One possible solution is to have a script that gets the
architecture based on the board being used. Attachments

Other IOs use this format, so lets be consistent and use
I2C_0 instead of I2C0 and I2C_1 an instead of I2C1.

This patch replaces all occurences of the macro DEV_OK by the actual
value 0 at the driver level. So this patch touch the files under
drivers/, include/ and samples/drivers/.
This patch is part of the effort to transition from DEV_* codes to
errno.h codes.

This patch fixes the QMSI I2C shim driver so we are able to use it in
Quark D2000 based platforms. The only change required to enable this
driver is an #if guard in i2c_qmsi_init() because the macro QM_I2C_1
is not defined in QMSI headers from Quark D2000.
Since this drivers is now properly tested with Quark D2000, this patch
sets the QMSI driver default options in arch/x86/soc/quark_d2000/Kconfig.
It also adds the wiring information required to test the i2c_lsm9ds0
sample app in the Quark D2000 CRB.

This patch adds a new sample application to demonstrate how to use
I2C APIs. The application is very simple. It simply reads the 'WHO
AM I' register from the accelerometer in the LSM9DS0 chip and check
if it matches with the value described in the datasheet.
It also adds a README file which provides the wiring information
required to get the sample application working on Quark SE DevBoard.
